21-Aug-06 | STEREO delay, again

STEREO has been delayed again, this time until the opening of its next group of launch windows, no earlier than 18 September. Follow-up analysis of a similar second stage tank revealed that it “was marginally thin in an area of the oxidizer tank. Engineers are assessing several options for the STEREO launch vehicle… to determine the thickness of the tank in this same area.” Another round of de-stacking may be needed. The STEREO spacecraft have been stacked atop the Delta third stage and sealed inside a transportation canister, but will remain in the Astrotech payload processing facility until this issue can be resolved.
